PROTECTION DESCRPTION:
Battery Polarity Reverse Protection
: when the battery polarity is reversed, the
BATT indicator light will display RED and the BATTERY and LOAD terminals will
terminate output. Battery reverse will not damage the model if the AC power is off.
The AC switch must be turned off at any time when the battery is changed. If AC is
on and the battery is connected, the PS polarity reverse protection is disabled, and if
the polarity is reversed again, the fuse of the PS will be burnt, sometimes causing a
spark.
Battery Low Voltage protection
: When the AC is OFF or has failed, if the battery
voltage is lower than 21V±0.2V, the model will turn off the battery and the output on
LOAD. When AC returns or the battery voltage returns to 25.2V±0.2V, then the
output on LOAD will recover automatically.
Load Over Current Protection
: the model will automatically shut down if the load
is over 8A. when the load is reduced, the PS will auto recover.
Load Over Voltage Protection
: when the LOAD output is over 30V, the PS will turn
off.
Load Short Circuit Protection
: output terminal short circuit will not damage the PS,
it will be simply stop the output. When the short circuit status is removed, the LOAD
will recover immediately.
